RPM resource perl-Exporter

The Exporter module implements an 'import' method which allows a module to
export functions and variables to its users' namespaces. Many modules use
Exporter rather than implementing their own 'import' method because
Exporter provides a highly flexible interface, with an implementation
optimised for the common case.
Perl automatically calls the 'import' method when processing a 'use'
statement for a module. Modules and 'use' are documented in the perlfunc
manpage and the perlmod manpage. Understanding the concept of modules and
how the 'use' statement operates is important to understanding the
Exporter.
How to Export

which they can request to be exported, respectively. The symbols can
represent functions, scalars, arrays, hashes, or typeglobs. The symbols
must be given by full name with the exception that the ampersand in
front of a function is optional, e.g.
